--- Comment #1 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2011-10-27 18:01:17 UTC --- Created attachment 25636 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25636 aoa.c C source file that has several call to printf-ish function. With the current implementation, after each call the code must get rid of the pushed arguments which is expensive as SP cannot be modified directly. Compile with, e.g., $ avr-gcc aoa.c -S -Os -mmcu=avr4
